40. Current endoscopic closure techniques for the management of gastrointestinal perforations.

Abstract

Acute gastrointestinal perforations occur either from spontaneous or iatrogenic causes. However, particular attention should be made in acute iatrogenic perforations as timely diagnosis and endoscopic closure prevent morbidity and mortality. With the increasing use of diagnostic endoscopy and advances in therapeutic endoscopy worldwide, the endoscopist must be able to recognize and manage perforations. Depending on the size and location of the defect, a variety of endoscopic clips, stents, and suturing devices are available. This review aims to prepare and guide the endoscopist to use the right tools and techniques for optimal patient outcomes. [ABSTRACT FROM AUTHOR]

41. Endoscopic ultrasound‐guided gallbladder and bile duct drainage with lumen apposing metal stent: A large multicenter cohort (with videos).

Abstract

Background and Aim: Cholecystectomy and endoscopic retrograde cholangiopancreatography are the gold standard for managing acute cholecystitis and malignant biliary obstruction, respectively. Recent advances in therapeutic endoscopic ultrasound (EUS) have provided alternatives for managing patients in whom these approaches fail, namely, EUS‐guided gallbladder drainage (EUS‐GB) and EUS‐guided bile duct drainage (EUS‐BD). We aimed to assess the technical and clinical success of these techniques in the largest multicenter cohort published to date. Methods: A retrospective, multicenter, observational study involving 17 centers across Australia and New Zealand was conducted. All patients who had EUS‐GB or EUS‐BD performed in a participating center using a lumen apposing metal stent between 2016 and 2020 were included. Primary outcome was technical success, defined as intra‐procedural successful drainage. Secondary outcomes included clinical success and 30‐day mortality. Results: One hundred and fifteen patients underwent EUS‐GB (n = 49) or EUS‐BD (n = 66). EUS‐GB was technically successful in 47 (95.9%) while EUS‐BD was successful in 60 (90.9%). All failed cases were due to maldeployment of the distal flange outside of the targeted lumen. Clinical success of EUS‐GB was achieved in 39 (79.6%). No patients required subsequent cholecystectomy. Clinical success of EUS‐BD was achieved in 52 (78.8 %). Thirty‐day mortality was 14.3% for EUS‐GB and 12.1% for EUS‐BD. Conclusions: EUS‐guided gallbladder drainage and EUS‐BD are promising alternatives for managing nonsurgical candidates with cholecystitis and malignant biliary obstruction following failed endoscopic retrograde pancreatography. Both techniques delivered high technical success with acceptable clinical success. Further research is needed to investigate the gap between technical and clinical success. [ABSTRACT FROM AUTHOR]

Abstract

Introduction. Adenocarcinomas account for approximately 40% of small bowel cancers. They are typically mucosal lesions with distinctive features on endoscopy. We describe a rare case of duodenal adenocarcinoma presenting as a subepithelial lesion which posed a diagnostic challenge. Case. An 85-year-old male patient presented for investigation of iron deficiency anaemia. Initial upper endoscopy found a subepithelial duodenal lesion with central depression but otherwise normal appearing mucosa. Superficial biopsies of the duodenal lesion were unremarkable. Subsequent antegrade single balloon enteroscopy revealed active bleeding from the lesion which was refractory to endoscopic treatment. A complete local excision of the lesion via laparotomy was necessary to achieve haemostasis. Histopathology from the lesion showed a moderately differentiated duodenal adenocarcinoma with invasion into the submucosa but no evidence of lymphovascular spread. Conclusion. Duodenal adenocarcinomas are rare gastrointestinal tumours associated with a poor prognosis. This case report outlines a rare presentation of duodenal adenocarcinoma and highlights the importance of judicious assessment of lesions found on endoscopy. Advances in endoscopic diagnostic modalities could facilitate early diagnosis and improve therapeutic outcomes.

46. Endoscopic bariatric therapies for obesity: a review.

Author

Staudenmann, Dominic A, Sui, Zhixian, Saxena, Payal, Kaffes, Arthur J, Marinos, George, Kumbhari, Vivek, Aepli, Patrick, and Sartoretto, Adrian

Abstract

▪ Obesity is reaching pandemic proportions globally, with overweight or obesity affecting at least two-thirds of Australian adults. ▪ Bariatric surgery is an effective weight loss strategy but is constrained by high resource requirements and low patient acceptance. ▪ Multiple endoscopic bariatric therapies have matured, with well established and favourable safety and efficacy profiles in multiple randomised controlled trials (RCTs), and are best used within a multidisciplinary setting as an adjuvant to lifestyle intervention. ▪ Three types of intragastric balloon are currently in use in Australia offering average total weight loss ranging from 10% to 18%, with others available internationally. ▪ Endoscopic sleeve gastroplasty produces average total weight loss of 15-20% with low rates of severe complications, with RCT data anticipated in December 2021. ▪Bariatric and metabolic endoscopy is rapidly evolving, with many novel, promising therapies currently under investigation.

50. Endoscopic modalities for upper gastrointestinal leaks, fistulae and perforations

Abstract

Background Endotherapy techniques are a recent addition to the suite of non‐surgical and minimally invasive strategies to manage patients with perforations, leaks and fistulae. The emergency nature of these conditions and the heterogeneity of pathologies encountered create difficulties when trying to select appropriate tools in these complex situations. The purpose of this article is to review experience at a tertiary academic centre, describe the various endoscopic tools available and the situations where they can be considered for use. Methods Single‐centre series and review of the published literature. Results Of 64 patients, 57 were successfully treated using endoscopic therapy, with surgery used only to provide drainage and suture fully covered metal stents in place to prevent migration. Discussion Selection of an appropriate endotherapy or stent for a patient with an oesophago‐gastric perforation or fistula requires an understanding of the anatomy and physiology underlying the patient's presentation and an understanding of the strengths and weaknesses of the available methods. Standard surgical principles of drainage, avoidance of distal obstruction and nutrition remain central to successful outcomes. A combination of surgical and endoscopic treatments may reduce the number of required treatments and can provide the ability to anchor fully covered stents to prevent them from migrating.
